Describe your issue:

My problem is as follows,

I have bought the BTT MINILCD V2.0 for my printer and would like to put it into operation.

Unfortunately, I always get an error message when I restart the firmware. I have attached a picture of the error message.

Here is an excerpt from my Printer.cfg

If I comment out the lines under [display] the printer works again and the lines with Neopixels work perfectly and I can change the colors as I like.
I hope it’s a simple error and I’m just blind and don’t see it

You are running an unofficial Klipper version on your board and in combination with the Klipper running on the host (which looks suspicious as well), it is creating strange errors.

Thanks for the quick answer.

Hmm ok I try to do a fresh reinstall on the MCU.

Please don’t throw stones at me but my host is the Sonic Pad, I thought last year that would be the solution to all my problems but it’s rather different, I’ll probably have to get a Pi soon :slight_smile:
